4 Claims. l

The present invention relates to air conditioning of houses, and more particularly to a system for supplying the rooms of a house with fresh wholesome air in a manner to reduce the room temperature in summer and to ensure increased heating eciency in winter. The system applies to houses having air heating furnaces in the basements, as well as to houses having stove heat, and both of these arrangements will be described herein.

My invention is fully described in the following specification and illustrated in the accompanying drawings, wherein like reference characters indicate corresponding `parts throughout the several views.

In the accompanying drawings:

Figure 1 is a horizontal section through the rooms on the first floor of a house having a hot air furnace in the basement, radiating air outlet conduits being extended from the furnace jacket.

Figure 2 is a vertical section taken on line 2 2 of Figure l.

Figure 3 is a fragmentary Vertical section taken on line 3-3 of Figure l, and showing the base-y ment wall of Figure 2.

Figure 4 is a fragmentary section of a basement corner, wherein hollow tiles are used to form air flues in the walls of the basement.

Figure 5 is a front view, partly in section, showing the hollow tile wall construction provided with an air choke or baffle and a partition for dividing the air ducts or ues and changing the direction of air flow to the furnace.

Figure 6 is a fragmentary elevation showing a modification of the basement wall constructed of hollow tile and having air ducts, the direction of air iiow being indicated by arrows.

Figure '7 isa View partly in elevation and partly in section, more clearly showing the partition arrangement of Figure 5.

AReferring first to the embodiment of Figures l to 7, inclusive, Figure l shows the iirst floor plan of a house having several rooms on the floor, as indicated at A, B, C, D and E, respectively` Beneath near-the-ceiling vents 2| and opening into the horizontal passages 22 in the porous hollow tiles 23 of which the basement walls are constructed. The vents 2l have cut-o shutters 2 I The basement walls are erected on a concrete door 36 and have an outside layer 24 of concrete and an inside lining 25 of cement. The tiles are'laid with their passages 22 aligned and continuously running horizontally so as to open into a metal coping 26 forming an air inlet to the jacket Iii of furnace I5. In the coping 26 is mounted a fan blower 2l which draws air in through the near-the-ceiling Vents 2 I, or through floor Vents `I 9 which open into the vertical channels 26, and then through the horizontal tile passages of the basement walls into the coping 25. The fan blower 21 discharges this air into the furnace jacket I6 after having been cooled and moistened in its circuit around the building, and the air is then returned to the rooms through the pipes I'I and wall registers Iii.

Below the channel 2l! which is located nearly opposite or most remote from lthe furnace, the tiling is provided with a vertical partition '39 in order to divide the air intake -to the furnace from both sides, as indicated by the oppositely directed arrows in Figures 5 and 7. An air duct yarrangement for equalizing the lengths of air flow is seen in Figure 6, where arrows indicate the directions of air flowl This arrangement is provided where a partition P is provided between adjacent rooms and air channels 2da extend downwardly from near-the-ceiling vents at opposite sides of said partition P, It will be noted that the air flows from the channels 29a into upper ducts of the adjacent portion of the tile wall for flow in a direction away from the furnace until- `it reaches the partition 3G in said wall for being subsequently returned in the Vopposite direction through the lower ducts of said wall portion to the furnace.

In Figure 5 is shown still another manner of equalizing the length of air flow, wherein an air choke 22 is provided between sections of the wall beneath a channel 2i! located near the furnace. The choke 29 consists of a diagonally placed plate for diverting the air from channel 2li in a direction away from the furnace through the 'upper ducts of a portion of the tile wall, for being subsequently returned in the opposite direction through the lower ducts of said wall portion after reaching the partition 3G of vFigure 5 or '7.

in the operation of this embodiment 0f the invention, air is drawn from adjacent the ceiling through the near-'the-ceiling vents down through the wall channels 2Q, through the hollow porous tiling to coping 25, and is then forced into the furnace jacket I6 for being subsequently expelled through the pipes H and wall registers I8. This operation is followed in summer, the shutters 2 l of vents 2l being open, and the shutters I9' of registers I9 being closed. In` winter the operation is the same, except that the shutters 2 l of vents 2l are closed and shutters i9' of registers I9 are opened, thereby causing the air to be drawn from the rooms at the floor instead of from near the ceiling. In summer, the furnace isof course not in operation, but in winter it is in operation `so that the system serves as a heat booster.

From the foregoing description, it is believed that the various embodiments, as well as the operation thereof, will be readily understood, and

the advantages thereof appreciated. Other modii'lcations will suggest themselves to those skilled in the art.

What I claim is:

1. In an air conditioning system for a house having rooms above the level of the surface of the ground and a basement below said level, basement side and end walls of concrete below said level, basement inner side and end walls formed of vertical rows of porous tiles laid adjacent to the concrete walls, the tiles having through passages extending lengthwise of the walls and laid end to end to form continuous elongated conduits one above the other, there being a. vertical outlet passageway in one of said tile walls into which passageway some of the conduits opensaid outlet passageway leading into the house above the basement, a vertical inlet passageway in another oiV said tile walls opposite said mst-mentioned wall and into which inlet passageway other ccnduits open, said inlet passageway leading from the interior of the house above the basement, a central vertical partition in said inlet passageway dividing incoming air and directing it in opposite directions into conduits opening into opposite sides of the inlet passageway and leading therefrom to the outlet passageway, other similarly leading vertical inlet passageways formed in said tile wall at spaced intervals along the perimeter of the basement, a diagonal baille in each of said lastmentioned inlet passageways extending from one side of the top of the passageway to a lower portion of the opposite side for directing incoming air to the upper conduits of said tile wall, said upper conduits leading to said first inlet passageway where the air is directed by said partition to the lower conduits leading, beneath said diagonal barile, to the outlet passageway.
